Continuity

As Madeleine leaves the florist in her Jaguar, Scottie follows her in his 1956 DeSoto, with license number HAF 376. However, 54 minutes into the movie, he follows her again, but the camera car, a similar DeSoto, with Scottie at the wheel, passes the HAF 376 licensed DeSoto which is erroneously parked at the curb.

Both times the main characters drive to the old mission, the wide shots show them driving on the right side of the road. However, all shots inside the car show them driving on the left side of the road.

When Madeleine is in Scottie's apartment after he rescued her from the bay, he offers her two cushions to sit on in front of the fireplace. When he picks up the cushions, they are green. In the next shot, when the cushions are shown hitting the floor, they are gold. When the cushions are shown lying in front of the fireplace after Madeleine has fled, they are green again.

As Scottie parks alongside Madeline in front of his apartment, his car (actually the camera truck) cuts across several parking spaces. When the angle changes and Scottie is shown stepping from his car, it is parked within one parking space.

Scottie is standing on the top of a step stool when he faints and falls. In the next scene Midge catches him after he falls only about one foot. Based on the height of the stool he should have fallen at least three feet.

During the opening scene when Scottie hangs onto the rain gutter, the tiling of the roof top he slid down from changes from flat wooden tilings to half-cylindrical brick tilings when the police officer returns to try save Scottie. Close-up shots of the police officer show half-cylindrical brick tilings while the medium shots with officer and Scottie hanging on show flat wooden tilings.

After Madeleine has talked to Scotty outside his flat and got into her car, a pedestrian is just about to cross the street in the background. The camera cuts back to Scotty following her immediately, but the pedestrian has disappeared.

When Scotty buys Judy a flower from the street vendor across from Ransohoff's they cut to a studio closeup of them that includes a large bunch of purple carnations which Judy brushes against as they leave, but when the scene returns to the location shot the flower bunch is nowhere to be seen.

Crew or equipment visible

As the camera moves away from Scottie standing at the edge of the tower, the shadow of the camera can be seen for a split second on the outer wall of the tower. On the Alfred Hitchcock Masterpiece Collection DVD, the image is cropped so the shadow cannot be seen.

When Scottie buys new clothes for Judy at Ransohoff's, Judy is shown trying on a pair of shoes. Due to the extremely low camera angle when Judy walks away from the camera, it's easy to see that the shoes are not new- their soles are heavily scuffed.

When Madeleine arrives at Scottie's apartment to post a letter, the establishing shot shows only a few bushes by the metal railings. However, in the closer two shots, more bushes are can be seen against the railings.

Madeleine enters the McKittrik Hotel and the sky is overcast. When she appears in the window of the 2nd floor room, she is clearly illuminated as from sunlight, throwing a distinct shadow against a light background, while the rest of the shot remains illuminated modestly (possibly assembled footage).
